Chris Brown -- Graffiti Scofflaw

Seems like Chris Brown has pissed off a whole new batch of neighbors, and he didn't even have to savagely beat anyone ... all he had to do is some serious tagging.

Chris' Hollywood Hills home is now bedazzled with huge graffiti murals. Chris is a talented artist and the works have markers that make it look like he did it himself ... but we can't confirm it.

But as pretty as it is ... it ain't sitting well with Chris' neighbors, who called L.A. City Councilman Tom LaBonge, complaining it was a blight on the block.

LaBonge passed it on to L.A. City officials, and Chris was cited for having "unpermitted and excessive signage" on his property. If he doesn't remove the murals STAT ... he'll be fined.

It could be the complaints are the proverbial nuclear fight over how a married couple squeezes a toothpaste tube. In other words, there are deeper problems ... in this case we've learned neighbors are royally pissed off at the loud parties Chris throws at all hours of the night. They've also had it with cars speeding up and down the street.
